Atomtronics deals with matter-wave circuits of ultracold atoms manipulated through
magnetic or laser-generated guides with different shapes and intensities. In this way, new …

Abstract The Sachdev–Ye–Kitaev (SYK) model is a strongly coupled, quantum many-body
system that is chaotic, nearly conformally invariant, and exactly solvable. This remarkable …

We review recent progress and future prospects for harnessing powerful tools from
theoretical high-energy physics, such as scattering amplitudes and effective field theory, to …

A bstract It was noticed many years ago, in the framework of massless RG flows, that the
irrelevant composite operator\(\mathrm {T}\overline {\mathrm {T}}\), built with the components …

A bstract We present the complete formula for the cusp anomalous dimension at four loops
in QCD and in maximally supersymmetric Yang-Mills. In the latter theory it is given …

A bstract Quantum complexity, suitably defined, has been suggested as an important probe
of late-time dynamics of black holes, particularly in the context of AdS/CFT. A notion of …

We review recent progress in understanding the notion of locality in integrable quantum
lattice systems. The central concept concerns the so-called quasilocal conserved quantities …

Technological advances in controlling and manipulating fluids have enabled the
experimental realization of acoustic analogues of gravitational black holes. A flowing fluid …

Outlining a revolutionary reformulation of the foundations of perturbative quantum field
theory, this book is a self-contained and authoritative analysis of the application of this new …

A bstract In the AdS/CFT correspondence, amplitudes associated to connected bulk
manifolds with disconnected boundaries have presented a longstanding mystery. A possible …
